Deputy White House spokesman Trent Duffy, said the administration had declined requests to provide sworn testimony to two congressional committees by Andrew Card, the White House chief of staff; Card's deputy, Joe Hagin; Frances Fragos Townsend, the domestic security adviser; and her deputy, Ken Rapuano.
"The White House and the administration are cooperating with both the House and Senate," Duffy said. "But we have also maintained the president's ability to get advice and have conversations with his top advisers that remain confidential."
